OpenAI's revenue run rate tops $40 billion ahead of its planned IPO

OpenAI’s annualized revenue run rate has surpassed $40 billion, about double the $20 billion it reported at the end of 2025, according to people familiar with its finances.

The doubling, reached in months and just ahead of an expected initial public offering, shows how fast spending on artificial intelligence is compounding across consumer and enterprise customers. Monthly revenue run rate grew more than 20% in July alone, Co-founder and President Greg Brockman reportedly told staff in an internal update.

The growth is attributed to subscription services, early advertising efforts and specialized software, including the Codex coding agent and the ChatGPT Work enterprise product. OpenAI has also cut prices on some models and hired a new chief revenue officer to push enterprise sales.

For scale, rival Anthropic reported a $47 billion run rate in May 2026, though differences in how the two companies account for revenue make a direct comparison unreliable.

OpenAI has not published the $40 billion figure, and it is not audited. Chief Financial Officer Sarah Friar previously said the company closed 2025 with an annualized run rate above $20 billion. A run rate annualizes recent revenue and can overstate a full year when growth is front-loaded, so the number describes momentum more than booked sales.

The IPO will force OpenAI to disclose figures it has so far kept private, testing whether the run rate holds up under audited accounting.
